Calculates the harmonic mean[1] of the values in a data set.
The harmonic mean is the reciprocal of the arithmetic mean of the reciprocals of the values.
Syntax:
HARMEAN( list )
Returns the harmonic mean of the values in the list.
list may be a range of cells, an array, or a comma-separated list of values (which may contain cell references and also ranges of cells as one or more of its elements).
All values in the list must be non-zero numbers.
Formula:
HARMEAN = ( i ∑1n 1 ∕ xi ) ∕ n
where n is the number of values and xi is the i‑th value.
Example:
HARMEAN(A1:A15)
returns the harmonic mean of the contents of cells in the range A1:A15
